This edited volume focuses on the use of Computational Communication Science (CCS) to address key questions in political communication, highlighting methodological innovations and the theoretical, practical, and institutional challenges in the field. Topics include clickbaiting, propaganda, political polarization, and media framing.

Yannis Theocharis holds the Chair of Digital Governance at the Technical University of Munich. His research interests are in political behavior, political communication, harmful speech and content moderation and computational social science. He is a core member of the Munich Data Science Institute and director of the Content Moderation Lab at the TUM Think Tank.

Andreas Jungherr holds the Chair for Political Science, especially Digital Transformation at the University of Bamberg's Institute for Political Science. His research explores the impact of digital media on politics and society, with a particular emphasis on algorithms, artificial intelligence, and governance. He also investigates the challenges scientific research faces in response to digital change, aiming to unlock the opportunities presented by new data sources and analytical methods. His work centres on leveraging digital methods and computational social science, while also addressing the methodological challenges of integrating these approaches into the social sciences.
